Hi,\nI have speakers Klipsch RP-8000F and I am looking for a new Amplifier. \nI would definitely choose a Yamaha one. However, I am struggling to find the difference between the two aforementioned . \nCan you please explain the real advantage of the former, if there are such? Why would you choose one or the other?\nThe question was provoked due to the prices in Canada - $1300 for A-S801 vs $1000 for the R-N803.\nThe question is, what is so much better in the A-S801 to cost more, while R-N803 offers a receiver with WiFi, etc?\n\nThank you in advance.
